how to find a bass + kick sample for djing

I've been having this problem for some time now.
I try to use my own kick instead of the bass of the main song I'm playing. I haven't created my own studio yet so I'm very new to creating music or samples. I used samples I found from the internet but I cant find a good bass+kick sample so I only use 1 shot kick which sounds fine when I'm playing at home to myself but its obviously weak when you play it to a crowd with a high volume.

What I'm looking for is simple bass and kick sound with no melody but just 1 shot sample. I mostly use 3-4 decks at the same time to create something new live and the music I play is very similer to Luciano from Cadenza which is minimal/techno so I want to give example from his sets. He creates his own samples so he doesnt have a problem with playing sophisticated sets but I'm dying out here deth

For example he used only one sample for his bass-kick lines for one of his 6 hours set in Romania. The sample fits with literally every song. I want to find something like this until I have the chance to create my own.

Is this impossible or wrong in anyway I'm not aware of?
